Serial No. 669,671.

lb all whom it may con-carn- Be it known that 1, MAX VOGEL, a subject of the Emperor of Germany, and residing at Schafergasse 10, Frankfort on the Main, Germany, have. invented a certain new and useful Improvement in stapling-Pliers, of which the following is a specification.

The object of the invention is to provide a stapling-pliers which grip the articles to be secured together before the staple driver is driven through the work.

ith this object in view the invention consists in the especial arrangement of the springs adapted to hold the jaw of the pliers in open position. which springs are secured on such places of the levers that they are not in the way if the casing containing the staples to be fed to the jaw is to be opened or otherwise is to be acted upon.

A further object of the invention is to secure the pliers from becoming obstructed by a staple not wholly driven out of the guideslot, which is obtained by the arrangement which are fed in the known manner as for instance by the device shown in Fig. 6 or Fig. 14. The casing 15 is mounted on a pin 16 in the manner as hereinafter described with respect to Fig. 6 and is loosely in en gagement with the inner sides of the levers l7 and 18, respectively, formed of sheet metal and connected by the pin 16 on which they are adapted to rock together with the staple casing 15. The lever 17 carries the anvil 19 and a bolt 20, rigidly mounted on the lever 18 is connected with the staple driver 21. Said driver moves in a guideslot 22, formed in the head of the staple casing or box, and to which a staple is automatically fed when the jaws of the pliers are closed. The end of the bolt 20 is screw- 1 threaded for the provision of a nut 23 against which the driver 21 is pressed by means of a spring 21 arranged between th end of the lever 18 and the driver 21. Said spring, furthermore, tends to keep the driver in its uppermost position by rocking the lever 18 as far as possible apart from the casing 15. A second spring 25 connected with the anvil 19 and the lever 18 tends to is a side elevation, Fig. 2 a plan view, and I keep the jaw open. Said spring 25 is fas- Fig. 3 an end elevation of the jaw of the j tened with its one end to a pin 26 fixed on pliers.

Continued movement of the levers in of the jaw parts of a furth r odifi d sta the same direction causes the staple driver lingli r arts of th levers b ing brok n to descend in its guide-slot pushing the foreawav.

The

In the'modification shown in Figs. 4 to 8 the parts of the pliers correspond to like parts of the pliers described with respect to Figs. 1 to 3 with the sole exception that the bolt 20 is provided with a recess 28 the object of which, hereinafter, will be described.

. 15 denotes the staple casing. Said staple casing 15 is loosely mounted on the pin 16 by means of lugs 29 protruding from its underside and embracing said pin 16 in such a manner that the casing may be rocked about the pin 16. The casing, furthermore, is U-shaped in cross-section and is provided with a removable cover 31 guided in ears 30 attached to or integral with the lateral upper edges of the casing. The cover 31 is arched as shown in Fig. 9 in such a way as to be able to take up a rod 32 carrying a spiral spring 33 which tends to push a staple feeder 34 toward the head of the casing 15, said feeder engages the rod 32 by means of a sleeve 35 adapted to be displaced longitudinally on the rod 32. Fastened by rivets 36 a staple carrier 37 is mounted in the U shaped casing 15 the rearward end of which is closed by a block 38 attached to the rod 32. In order to hold said block in place a fiat spring 39 is fixed to the underside of the casing and is provided with a hole 40 that is engaged by a pin 41 .of the block when the same closes the casing as shown in the Figs. 6 and 7. The spring 33 being compressed between said block 38 and the feeder 37- tends to feed the staples forward to the head portion of the casing where an opening is arranged having an area corresponding to the size of a staple and through which the staples are fed into the slot 22 formed in said head portion. In order to refill the casing it only is necessary to push the spring 39 down thereby releasing the block 38 so that by the action of the spiral spring 33 the block may be spaced apart from the rear end of the casing and may be gripped by hand. The rod 32 with the feeder may then beremoved from the casing as well as the cover 31, if desired, the rearward end of same abuts against the block 38 when in position and is, therefore, protected from sliding out of the ears 30 by means of said block 38. In order to facilitate the refilling of the casing the side walls and the bottom of the rear end of the casing are prolongated over the end of' the staple carrier 37 and when the block 38'is removed the front end of the. known wooden staple carrier may be inserted into the rear end of the casing where it is held in proper position with respect to the carrier 37 so that the staples easily may be fed by hand from the wooden carrier to that one mounted in the casing. As already explained the foremost staple is fed by means of the feeder 34 into the guide slot 22 of the driver and just below the same. The latter in descending pushes said staple along the slot until it is clenched upon the anvil 19. The driver then ascends while the aperture, through which the bolt 20 passes, is sliding on the bolt 20 until the driver reaches a recess 28 by which it is stopped in its motion as its aperture engages said recess 28, the pliers now are locked. In this position of the driver the aperture for the staples through which they are fed into the slot is partly closed by the lower edge of said driver preventing in such a manner the feeding of the staples. In

case a further staple is to be inserted into 7 the papers the levers first are to be closed whereby no staple can be driven intothe documents as there is none in front of the driver, and then suddenly are'released. The hole of the driver, now, will not be caught by the recess 28 but will freely pass over same until the nut 23 abuts against the driver. The latter in its end position has cleared the aperture for the delivery of the staples so that the foremost one, now, can be fed below the driver, which with its next downward motionpushes same into the papers to be fastened together. The operator, therefore, according to the quickness of the releasing movement of the pliers is free to look the driver or to bring it back into its initial position. Now, in order positively to obtain said locking position the device shown in theFigs. 9, 10, 11 and 12 is' arranged on the side of the head of the casing. Said device consists of a lever 50 loosely secured to the head of the casing 15 by means of a pin 51 and a slide 52 adapted to be moved longitudinally on the enlarged end 53 of the lever 50. The enlarged end 53 as well as the slide 52 are slotted and engage a pin 54 fixed to the lever 18. The slot in the slide is somewhat shorter than the slot in the enlarged end and each slot is provided with a recess 56 that in a predetermined position of the slide on the lever register with each other. A spring 55 tends to rock the lever 50 in such a way that the pin 54 is in perpetual engagement with that side of both slots in which the recesses are located. In consequence thereof the pin engages the recesses 56 in case both should register. As shown inFig. 9 in open position of the pliers the pin 54 abuts the upper end of the slot in the slide and of the enlarged end 53 and both recesses 56 regis= ter with each other. In closing the pliers or in imparting a downward movement to the driver the pin 54 moves along the slots and is caught by the registering recesses so that the movement of the driver is stopped while the levers are locked against retrograde movement. In consequence thereof the aperture through which the staples are fed into the guide slot remains closed and an introduction of a further staple into the guide-slot is positively prevented. In case lower end of the driver could return in its initial position without having pushed the staple in front of it out of the ide the introduction aperture would be c cared a second time and a second staple would be allowed to enter the guide slot now containing two staples which obstruct the guide. This disadvantage is dispensed with if the driver be allowed to return in its original position but after it has done its full stroke and has driven out of the guide the staple contained therein. After the pin 54has been caught in the recess 56 the levers can yet be closed farther until the pin 54 strikes the end of the slot in the slide, which on continuous closing movement pushes the slide downward, so that the two recesses come out of register. The pliers being closed the pin 54 abuts the the slot in the enlarged end of the lever 50 while the upper end of said slot is now covered by the slide. In releasing the levers the springs 24 and 25 will bring same in the open position, the pin 54, during said movement, passes over the recesses as they do not register with each other and pushes the slide back into its original position, in which the recesses 56 register.

At the same time the introduction opening in the casing is cleared from the driver and a fresh staple can be fed into the guide-slot below the driver. The pliers now are ready for use for the next stroke.

In the Figs. 13, 14 and 15 a modified form of the casing is shown. The casin 60 which is hinged to the pin 16 as herembefore described is provided with a cover .61 adapted to be slipped below the ears 62 attached to or formed integral with the side walls of the casing. The latter contains the staple carrier 63 constructed somewhat shorter in length than the casing, the rear end of which protrudes over the carrier for the purpose as set forth hereinbefore. At the rear end of the casing each side wall is slotted as indicated by 64 for the insertion of a two armed lever 65, having rounded ends, fixed on a rod 66 which is engaged by the sleeve 67 of the staple feeder 68. The latter embraces the staple carrier 63 on three sides and'is pushed toward the head of the casing by a spring 69 coiled upon the rod 66. Loosely mounted on the rod is a plate 70 of such dimensions as to close the rear end of the casing if brought into the position shown in Fig. 15. On said plate 70 a lug 71 is arranged and adapted to act upon the lever 65 in case the latter is put close to the plate 70. On the lever 65 :1 lug 72 or a pin is provided which engages a corresponding aperture 73 in the plate 70 if the lever is brought to register with same, as represented in Fig. 15.

In operation after the staples had been fed to the carrier 63 the feeder 68 is put on same and then by the engagement of the rod 66 carrying the spring 69 with, the

sleeve 67 the rod is pushed'into the casing pressing the spring 69 together between the feeder abutting the rearmost staple and the plate 70. Said plate is then inserted into the rearopen end of the casing which is closed by said plate. In this positionthe two armed lever 65 abuts against the plhte and by a suitable rotation of the rod 66 by means of the knob preferably attached to its end the outermost parts of the two arms engage the corresponding slots 64 so that the plate 70 is firmly held in position and cannotbepushed out of the casing. The two armed lever 65 is secured from rotation by the pin 72engaging the aperture 73 in the plate 70 and by the lug 71 which one arm of the lever lies against. In order to open the casing it is only necessary to rotate the lever 65 in the reverse direction so that its arms clear the slots 64 whereupon the rod 66 with the feeder 68 may then be removed from the casing.
